1028 | | By default, the advection scheme and the timestep scheme to be used for the subgrid-scale TKE are set by the initialization parameters scalar_advec and timestep_scheme, respectively. use_upstream_for_tke = .T. forces the Euler-scheme and the upstream-scheme to be used as timestep scheme and advection scheme, respectively. By these methods, the strong (artificial) near-surface vertical gradients of the subgrid-scale TKE are significantly reduced. This is required when subgrid-scale velocities are used for advection of particles (see particle package parameter use_sgs_for_particles). |
